a plication t d" October 15,1924. sen rno. "viae'nf i My invention pertainsto slicing machines, "parent from thisdes'cription ta-kenin conneo and more particularly to the mounting means 3 of the slicing m achme knife.

tion with the drawing, in which,

In all slicing machines of this type, nowon -chine with my invention applied thereto taken on line 22 of F igfil trated in this application, a knife of "large p Y I ,7 v

7 h igi 8' 15 an enlarged verticalsection taken diameter is used, whichisnecessary due to the fact that the ax s of the knife of such a lira-chine 1s either fixed withregard to the "on line3-31 of Fig. 1 and M i Fig; 4- is a section siinilarto that shown in Fig. 2, but the chain housing,"which supports above the axis ofthedrive sprocket for the knife and its chain, and the knife axis is only swingable'on the axis of said sprocket, hnt is 7 not movable longitudinally of thFhasc, but constantly retains the radialdistanceffroin' in combiiiationwith"i l ng niac hine of sition, thus bringing the knife edge nearer the adjacent side or edge ofthe movable table.

whereonis'mounted a chainhousi'ng 11 used for supporting a rotatable circular knife 12. Said base is also provided*witl1"guide rods 13 on which a reciprocating-table 14 moves to sprocket; and no provision isn' adeforuse of thesame results and for properly slicing material to the same effect as 1s done with their large knife. Th1s ob ect1onis overcome w th feeding material "to the forward side "16 of table as it travels-adJacent said knifej In the modern slic ng machines; the circuin Fig. 1, and as may he observed therein, the, center axis of the knife is placed forward" from the verticalline through theaxis of the; drive sprocket. This arrangement makes it; k 1 a v hasits peripheral edge sharpened at theconto); side, as b'estfshown in'Fi'g. 3, toflplacethe cuttingedge adjacent thesi'de of table 14, and with such dished knives the plane ofthis cutting edge is generally placed parallel with sc d sideA'G; Whilewitha flat knife the plane ofthe knife nrust be placed at an angle to said from the vertical lineextendingthroughthe center axis of the drive sprocket; and thus with my improved mounting means I utilize and purpose as the knife of larger diameter A with thefusual mounting means provided on and beveled edgecutastraight slice frointhe material, her-arise "theknife gets thickeri from the slnirpperipheral edge towards its center.

Another object isto variouslyu adjust the g I therefore provideyan ad ustaible mounting knife and its'supportingmeans so as to coininodern dishedand 'co'ncaved knife may he used 1 and mounte'djparallel to the table side 16, or aflat knifeinay also beused'wit-h my mounting means and mounted at an angle to said table side 16, as best shown in Fig. 4. Furthermore the knife edge wears'downwith constant use and the repeated sharpening thereof thus decreasing the diameteri ofthe knife, so I also provide my mountingmeans the knife edge, both radially and axially with respect to the movable table; and also to provide for use of knives of different shapes and convexity, and for mounting and adjusting the plane of the cutting edge of said knife either parallel to or at an angle with the side of the movable table, so as to utilize either a convex knife or a flat knife; and a further object is to mount the chain housing adjustably on the base so as to compensate for and to take up slack in said chain.

Other ob'ects and advantages are accomplished with my invention, as will become apradially nearer to the approaching tableto my adjustable mountingsmeans is arranged F ig. 1 is a side elevation of a slicingjnias Fig. 2 is an enlarged v, horizontal i section In the'drawing'l have shown my invention known construction, which includes a base 10 p and fro past said knife and carries a feed plate or material holder '15 for gradually mean'sfor saicl knifeso that either theiusual so that the knife may be moved and adjusted "Jill 1e knifo,is shown in a slanting or tilted po-r lar knifeis usually' dished oreonqav'ed and v table side 16 in orderjtohave the sharpened compensate for su'chwear; And in addition, d

to adjust the knife axially to further compensate for the receding of the knife edge in an axial direction, as best shown in Fig. 2. All

this adjustment "to compensate for such Wear, etc., I accomplish in a very simple an d inex pensive manner, and at the same time in an entirely practical and "efiici'ent manner; pref erab'ly by providing the chain housing 1'1,

' threaded into openings21 in the adjacent top,

which acts as a knife support, with horizontal supporting flanges 18, and resting these upon the topof base 10, and further providing these flanges with enlarged openings or-slots 19 through Which loosely extend bolts 20,

of base 1 0. I further place a disc or washer 22 between the head of a bolt andthe flange 1'8, on oneside'of said chain housing, and a 7 like washer between't-he head of a similar'bolt 20 and the bottom plate 24 of an M11 25 which supports the knife. guard 26' and rests on the flangeat the other side ofsaid, housing, toaid in clamping thefl anges firmly in position.

By loosening the bolts 20 theknife with its v support, namely the chain housing, maybereadily moved and'adju'sted axially of the knife as well as radiallyof said knife, as indic ated in dot and dash lines in Fig. 2, to

, provide for a new knife or fora knife of 5 greater onvexaaand after continual use to Plate/ 15v m iin' ed t r ii i- Thisadjusable mounting also "provides means for taking up a certain amount of slack in the chain 29 by .moving the chain housing 11 longitudinally jf, thebase, as indicated in dot and dash lines in Fig. 2 by bringing the driven sprocket (not shown) on the knife shaft 2 7 at'tlie upper part of thehousing ll, forward and further out of vertical alinement with the IOWQI? i p t'28- What Iclaim as my invention and desire to secure by Letters Patent-isi p I p 1. a In a slicing machine having a rotary circular knife and a tablernovable one wit-h respect to the other, means for adjustably mounting said knife with respect to said table to place the plane of the cutting edge of said knife at different angles with respect to the edge of said table.
